HARVESTER ELEVATOR-FRAM E.

SPECIFICATION forming part of Letters Patent No. 403,094, dated May 14, 1889. Application filed October 19, 1886. Serial No. 216,619. (No model.)

To all whom it may concern:

Be it known that I, JAMES E. DEERING, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Harvester Elevator- Frames, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof, wherein Figure l is a front elevation showing the side boards partly broken away to uncover the interior parts. Fig. 2 is a rear elevation with the side boards similarly broken away. Fig. 3 is a section through 0000 in Fig. 2. Fig. 4 is a perspective of the frame with the elevating-canvases removed.

A is the rear sill or frame-bar of the harvester.

A is the front sill.

B, B B and B are upright corner-posts at the inner forward, outer forward, inner rear, and outer rear corners, respectively, of the elevator-frame.

O C are respectively the forward and rear side boards of the elevator-frame.

D D and D D are respectively the lower and upper slide-bearings for the canvas elevating-belts. Said bars D and D are commonly called the canvas-slides, and will be so hereinafter designated.

D and D are respectively the upper and lower canvases or elevating-belts. They are provided in the usual manner with the crossstrips cl, which prevent the bagging of the canvases in the middle, and which bear on the canvas-slides D and D and thereby enable said slides to somewhat control the course of the canvases.

E E are sheet-metal plates placed on the inner surface of the side boards, 0' 0 respectively, as linings for the elevator-frame. The canvas-slides are secured inside said lining-sheets E E the fastening being most effectively made by bolts which pass through the canvas-slides and the lining-sheets and the side boards, and obtain their fastening in the corner-posts B 13 13 13 The same bolts thus become the fastenings, also, of the metallic lining-sheets E E which are thus bound with the side boards, 0 0 between the cornerposts on the outside and the canvas-slides on the inside.

The metallic sheet-linings E E serve the purpose of rub-irons, to prevent the canvases and the cross-strips wearing into the side boards, and thereby also diminishing the friction which would be caused simultaneously with such wear. Said metallic lining-sheets also serve the purpose of strengthening and stiffening the frame of the elevator, so that the side boards may be diminished in thickness much more than the amount of the thickness of the said lining-sheets, whereby, the space within the elevator and the width of the elevating-belts being undiminished, the

entire width of the harvester-frame from front I to rear may be diminished from one to two inches, saving that amount of metal in all bars and shafts extendingfore and aftthroughout the entire machine.

I find that by making these metallic liningsheets of about No. 18-gage steel-plate I can JAMES E. DEERING.
